Solve the equation: 3(x - 4) = -21
Stells [14]

Answer:

x= -3

Step-by-step explanation:

3(x-4)= -21

x - 4 = -7( to get this divide both sides of the equation by 3 )

x = -7 + 4 ( add 4 to both sides of the equation)

x = -3 ( then add -7 and 4 to get -3)

So clearly x = -3

Identify the slope in y=-x​
Norma-Jean [14]

Answer:

m = -1

Step-by-step explanation:

y = -x can also be written as

y = -1x + 0

The slope is -1.

In slope intercept equations, if the slope is '1' or '-1' they would usually drop the one.

Hope this helps.
